Emulate and Analyze Real Time IP Traffic in the Cloud

Service Providers and network equipment manufacturers now have the ability to emulate and analyse real time IP traffic in cloud environments for multiple hypervisors right down to each individual application flow.   With the migration from dedicated network boxes to flexible, fluid cloud environments you require a test capability that can work with dedicated environments or can operate in the new virtualized or cloud environment.

To test a cloud environment you need a completely virtualized test system to test opensource hypervisors as well as fully support vendor hypervisors. Shenick diversifEyeVM (Virtual Machine) can emulate and test a  Shenick Virtual Infrastructure Test & Measurement Solutions with multi-hypervisors, giving test analysis right down to each application so that virtualized networks run smoothly especially in extreme situations.

You now have more flexibility, scaling capabilities, easier software migration to virtual machine-based test and the ability to pin-point errors across layer 2-7 on a highly granular basis.  We can provide  powerful per-flow emulation and real-time analysis in VM-to-VM scenarios, and hybrid external-to-vm applications.diversifEye VM offers many advantages to the market:

  • Works with multi-hypervisors.
  • Offers no loss of functionality in combining real and VM test blades
  • Ensures the flexibility to add as many VM and virtual interfaces (VI) as required
  • Multiple VI per virtual test blades
  • Provides an easy, software-based migration path to an all-virtualized diversifEyeVM
  • Offers a vast range of application tests covering security, voice, video and data applications, as well as secure VPN offload/tunnel, address spoofing verification, DDoS attack mitigation test etc.

Telepresence Infrastructure Testing

Telepresence is the ability to conduct live meetings and simulate the attendee’s senses, by delivering high quality video and audio over an IP network.  To ensure you end up with the experience you want, each session is reliant on zero media faults and zero network interruptions.

To conduct a Telepresence meeting you connect multiple individual end-points to a central meeting management server. The server manages many aspects of the call including the video and audio distribution.  However, prior to commencing a call the unique remote end-points need to authenticate usually through a SIP registration server. Other components in a Telepresence deployment include meeting schedulers.

Testing your telepresence equipment is essential to ensure that you end up with the experience you want. Testing can be complex,  as a critical feature to testing Telepresence, is the ability to measure performance on each and every one of the 4 unique media flows (video  in – out and audio in – out) associated with each and every emulated test or end-point.   You may also want to inject traffic into the system so that you can disrupt the meeting, further testing the security and reliability of the deployment.


Sample Telepresence Test Scenarios

  • Live Meeting Performance:
    • Emulate and measure performance of the Telepresence meeting’s video and audio with stateful emulated end-points. Test for interoperability issues with end-points using different video and audio codecs.
  • Network Capacity Testing:
    • Examine network capacity with a small number and/or many emulated Telepresence end-points, threshold test acceptable packet loss.
    • Create real world scenarios with mixed application traffic loads. Examine the impact on each and every emulated Telepresence end-point’s video and audio quality.
  • Telepresence Meeting Scalability:
    • Test the registration server capacity to handle many registrations. Determine if a meeting manager server functionality handles over subscriptions to a meeting correctly. Emulate and analyze secure media sessions such as SRTP.

diversifEye Per Flow test platform allows you measure the characteristics on each and every flow using the following test scenario’s.

  • Stateful: Test end-points must communicate with 3rd party servers
  • TCP/UDP Aware: Capable of negotiating network control signals and requests
  • SIP Aware: Respond to SIP protocol requests
  • Application Aware: Test end-points should receive and transmit video and audio i.e. (4 x media flows)
  • Per flow Aware: Measure performance on each of the associated voice and video flows
  • Codec Independent: Test end-points can use a number of different codecs
  • Multiple Clients: The number of test points needs to be scalable

Testing DOCSIS 3.0

Cable providers are using DOCSIS 3.0 as an enabling technology.  To ensure the highest quality of service, a complete testing solution can allows you to verify compliancy and performance testing.

DOCSIS testing should include stateful two-way interactive flows.  To measure true quality of experience or service satisfaction require a ‘Per flow’ test approach in which stateful CPE traffic is presented on the cable modem to CPE Interface.  This allows you to test performance on an end-to-end basis from the CMCI (Cable Modem to CPE Interface) to CMTS-NSI (Cable Modem Termination System – Network Side Interface).  Performance testing includes everything from DHCP, IPv6 CPE behavior, QoS effectiveness and the upstream/Downstream channel bonding capability.

Shenick diversifEye “Per-Flow” Test System can deliver these capabilities.  This PDF is an overview of how diversifeye can help you with your testing requirements.
